The pinion posed between the roller l4 and said bearing I8. 50 is adapted to rotate freely about the stationary side portion 6, the top and side portions being cut pinion 50 and gear 5| is further limited by a suitaway at 6' to receive said roller, while a roller able locking sleeve 54 fixed to the stationary 15 26 is mounted in the frame at the junction of the shaft 32. lower portion 5 and said side portion 6.

The gear is keyed to the spincorresponding upper ends, meshing gears 63 and 80 adapted to-rot atably-receive or'journal a stationper surface of the gear 45. A worm 69 is carried ary mounting shaft 32 having a stationary pinion on the shaft 6|, above the roller 60 and is adapted 33'keyed thereto. to drive, through a gear 10, best seen in Figure 4 :5 is adapted rotatably to carry thereon a bobbin or Way thread 16. That is to say, the thread 16 is upper edge of th sleeve 31 fdr limiting downward its inner end portion with a socket 18 rotatably 0 mountingshaft fl and at right angles to the which i its end fixed 90mm length of said shaft, whilearelatively wide pinion 58, 8 gulde m r ding upwardly 5 is disposed beneath the portion 5. A stem '47 with member 82 including a pin 83 normally engagenuts 48 and 49 at opposite ends thereof, conable in the bayonet slot 8|.

then upwardly and again laterally'into the uppermost bayonet slot recess. The traverse. motion includes a feeder sleeve 84 which isscarried on the'traversemotion shaft 14 and is adapted'to be shifted'upwardly and downwardly on. said traverse motion shaft by rotation of saidshaft. That is to say, the beveled gears I2 and I3 cooperate to drive the traverse motion shaft and, as said shaft is driven, the feeder sleeve will be causedto shift upwardly on the threaded portion 190i said shj'aftQ The feeder sleeve 84 carries a gu'ide arm 294 which has its free end surroundingthe member I'll. The guide arm 284' serves to prevent rotation of the sleeve 84 and thus to insure vertical travel of said sleeve. After reaching the upper extremity of said shaft, the feeder sleeve will be caused to engage the counter-clockwise thread on said shaft 16 for shifting said sleeve downwardly. The feeder sleeve includesfa threadreceiving eye 95 which is formed integral with said sleeve.

In order to'provide a receptacle for the yarn twisted by my device, in a manner to be escribed hereinafter, I utilize a bobbin or package 86 which is removably carried in the flyer frame and which includes upper and lowerportions'fl and 89 and an axial stem 99; The portion 88, when the bobbin is mounted in'the fiyer' frame, is adapted to fit over the upper end portionof the package 'or bobbin mounting shaft 'inffric' tional engagement withthe friction disc 61 on the mounting plate 66.. The-upper portion of the bobbin is formed with a socket 99 which is adapted removably to receive the lower end portion of the latch member 82 when said latch: member is in its downwardly extended position. As heretofore stated,-for' dofling the bobbin, it is only necessary to shift the iatch member 8! upwardly so that said bobbin or package may be. freed fromsthe latch member and the package. mounting shaft.- The package mounting. shaft is".

, retained stationary with respect tothe flyer' frame 3 and with respect to the bobbin or' package 86. In order to retain the package mounti. ing shaft stationary, as. stated, I provide gears 9t and 92 which are'of the same size, relatively large, and are fixed to rotate with a shaft 98. The gear 9| meshes with the stationary'gear 33 on the stationary shaft 32 while the gear 92 meshes with a gear '94 which is fixed tothe package mounting shaft 99 near its lower end. It'

will be understoodthat, as the fiyer frame-Ira tates about the stationary shaft 32, the shaft 93 with the gears 9i and 92, will=be caused to move around with the fiver so that said gear 9| will be caused to rotate about thegea'r33 and, therefore, the gear 92 will be caused to rotate about the gear 94 so. that said gear 94, carried' by the shaft 39, will be maintained in a stationary position with respect to the flyer frame 3.

The shaft 39, being fixed to said gear '94 will, i I to the fee'd rollers, to the traverse motion-and of course, be retained stationarywith respect to}? the fiyer. A bushing. 94' separates the gear 94" from the pinion 44. i a

It should be understood that suitable hous ngs may be provided for all ofthe gearing so that;

oil used for lubricating the gearing will not corne""' in contact with threads being yarn on the bobbin. In use, threads from a plurality of bobbins 2 twisted or twisted on the creel I, which threads are indicated com-[j positely at 95, are led downwardlythrough the" compressors 95 which are ."mounted above; the fliers; The threads are ledfrom the compreshas been stated heretoforei. the former revolves to thesroller 2 4, along the top portion 4 of the flyer frame .3 therein, over the roller-25, down- ,wardly-' .through the side portion 6- o'f thej flyer f frame',.l about tharoller 26=,,a1on-g the bottom p'ortion 5 of the fiyesframeand partially about'fthe roller 21.

Moreover, the

slots 8, s and, to in t side: portion6' and top and bottom portions 4 and 5 respectively, permit easy placing of the, threads .in proper operative position. As the .threads -pass-flthrough the former, apartial twist is given to the'threads,'as stated, but, asv the -former; rotates at twice the speed of the h rerframe, dueuztoithe fant that down the. speed .of ;the fiyerq-frametwithrespect at the top of the flyerpof course- From partially about vthelro ller IL the nowhtwisted, yarn is led upwardly gthrough. thercompressor 38, through the opening 3,! and into-the socket 40;; partially about, the roller ;4 2-,: about "the feed rollers 59 and 69,- through the eyes Hand 99 formed [on the bracket ,55, through: the 'eye"95 andthence about thestemJQ of :th'e-bobbin' or package- 91. l yarn-.is'wourid about the feed rollers inlthe mannerbest seen in Figure 5-0! the drawings, 'and' .saidfeedrollers. are driven by:
